3.3 Constant Voltage Output Setting
Constant voltage output is the most common output of the power supply. The voltage output has a constant value in constant
voltage output mode, and it will not change with the load while the current will. The CV annunciator in the lower left corner of
the LCD will turn on when the power supply is in constant voltage mode.
1. Connecting a load to the relevant output terminals
Turn off the power supply. Connect the load to the relevant output terminals. Connect the positive pole of the load to “+”
terminal of the output, and connect the negative pole to “-” terminal of the output.
2. Turning on the power supply
Press the “Power on/off” button in the front panel. The power supply will go into power-on/ reset state,
namely the power supply is off.
3. Setting desired output voltage
The desired output voltage can be set directly by pressing number keys or using “Left/Right” key together with the knob.
1). Using number keys and “Enter” key to enter:
① Press “Vset” to enter into voltage setting state.
② Enter the desired voltage value by pressing number keys. “Clear” key can be used to clear any wrong value.
③ Press “Enter” key to confirm the voltage setting value.
2). Using “Left/Right” keys, knob and “Enter” key to enter:
① Press “Vset” to enter into voltage setting state.
② Press “Left/Right” keys to move the blinking digit to the relevant digit of the value.
③ Increase or decrease the relevant value by turning the knob clockwise or counter clockwise. Then use “Left/Right” keys to
move to the next digit to modify.
④ Press “Enter” key to confirm the voltage setting value.
4. Setting maximum current
The maximum current can be set directly by pressing the number keys or using “Left/Right” keys together with the knob.
1). Using number keys and “Enter” key to enter:
① Press “Iset” key to enter into current setting state.
② Enter the desired current value by pressing number keys. “Clear” key can be used to clear the wrong value.
③ Press “Enter” key to confirm the current setting value.
2). Using “Left/Right” keys, knob and “Enter” key to enter:
① Press “Iset” key to enter into current setting state.
② Press “Left/Right” keys to move the blinking digit to the relevant digit of the value.
③ Increase or decrease the relevant value by turning the knob clockwise or counterclockwise, then use “Left/Right” keys to
move to the next digit to modify.
④ Press “Enter” key to confirm the current setting value.
